Save hours/years of frustration when learning math:
Never before have I heard such a clear and concise explanation of the fundamentals... I seriously could have saved hours of hair-pulling in university had I had access to this article years ago.

I have several books on calculus (Calculus for Dummys, Math for the Millions, etc. etc. - never was able to read them) but your explanation is what I have needed all these years.

This is a great explanation! I am 49 years old and have never known what e is all about. It is thanks to your article that I get it and now can explain it to my son who is 13 years old...

Yes, we are making a triangle of sorts, and the hypotenuse is the distance from zero: Neat. While measuring the size isn’t as easy as “dropping the negative sign”, complex numbers do have their uses. Let’s take a look. A Real Example: Rotations We’re not going to wait until college physics to use imaginary numbers. Let’s try them out today. There’s much more to say about complex multiplication, but keep this in mind: • Multiplying by a complex number rotates by its angle Let’s take a look.

more growing things, which creates more growing things… your return adds up fast. The most basic type is period-over-period return, which usually means “year over year”. Reinvesting our interest annually looks like this: Math, Better 10 Interest Rates 104 of 144 Explained We earn $50 from year 0 - 1, just like with simple interest. But in year 1-2, now that our total is $150, we can earn $75 this year (50% * 150) giving us $225. In year 2-3 we have $225, so we earn 50% of that, or

think about what it means. The feeling of the equation. Make it your friend. It’s the calculus way of saying “Your rate of growth is equal to your current amount”. Well, growing at your current amount would be a 100% interest rate, right? And by always growing it means you are always calculating interest — it’s another way of describing continuously compound interest!
